Provided is a substrate processing apparatus. The substrate processing apparatus in which processes with respect to substrates are performed, the substrate processing apparatus includes a lower chamber having an opened upper side, the lower chamber including a passage allowing the substrates to pass therethrough in a side thereof, an external reaction tube closing the opened upper side of the lower chamber to provide a process space in which the processes are performed, an internal reaction tube disposed within the external reaction tube, the internal reaction tube being disposed around a substrate holder placed in the process position to define a reaction region with respect to the substrates, the substrate holder on which the one or more substrates are vertically stacked, the substrate holder being movable between a stacking position in which the substrates are stacked within the substrate holder and a process position in which the processes with respect to the substrates are performed, at least one supply nozzle disposed along an inner wall of the external reaction tube, the at least one supply nozzle having a supply hole for discharging a reaction gas, and at least one exhaust nozzle disposed along the inner wall of the external reaction tube, the at least one exhaust nozzle having an exhaust hole for suctioning an non-reaction gas and byproducts within the process space. The lower chamber includes an auxiliary gas supply port connected to the stacking space defined inside the lower chamber.
